Monoenergetic x-ray diffraction (XRD) analysis is an established standard for the assessment of urinary stone composition. The inherent low energy of x-rays used (8 keV), however, restricts penetration depth and imposes a requirement for small powdered samples. A technique capable of producing detailed information regarding component structural arrangements in calculi non-destructively would pr...

In this paper, we report the preparation and characterization of both the ZnO nanocrystalline thin films and nanopowder by ultrasonic spray pyrolysis technique. ZnO films were grown on polished Si(1 0 0) and amorphous glass substrates at different deposition temperature range varying from 200 to 500 1C. Both orientation and the size of the crystallites were found to depend on the substrate and ...

-X-ray powder diffraction (XRD) patterns for many interstratified mica/glycolated smectites were calculated by changing combinations of probabilities and transition probabilities of two-component layers. Three basal XRD reflections, 5.1L7.6~ (P l), 8.9 ~ 0.2~ (P2), and 16.1~176 (P3) were selected for the quantification curves. A distinct relationship exists between a20~ (p2 Pl) and A202 (P3 -P2...

Fig. S1 XRD patterns of ZnO NR, NC and NT arrays deposited on ITO substrates corresponding to Figs. 1i, 1iv and 2a, respectively, indexed according to the hexagonal wurtzite structure (JCPDS No. 36-1451). The peaks associated with In 2 O 3 from ITO substrates are labeled for clarity.

Activated carbon was treated at 5 GPa up to 1600 C, and the structural evolution in the graphitization process was investigated. The graphitization temperature is equal to 1200 C at 5 GPa, reflected by X-ray diffraction (XRD) patterns. Honeycomb-like structures in micron scale come into being in the high-pressure sintering temperature range of 100

Artemisinin (ARMN) is a potent antimalarial drug, which is effective against multidrug resistant strains of Plasmodium falciparum and produces rapid recovery even in patients with cerebral malaria. Being poorly soluble in water, artemisinin is incompletely absorbed after oral intake due to poor dissolution characteristics in the intestinal fluids. To enhance these properties, solid dispersions ...

X-ray diffraction is a commonly used experimental technique for identifying the structure of crystalline materials[3]. A crystalline material has its atoms arranged in periodic lattices with long-range symmetry. As a result, it scatters a beam of X-rays in well-defined patterns. Analysis of an X-ray diffraction pattern produced by a material yields extensive information about the structure of t...
